BLH Nobel Introduced a System That Quickly and Easily Checks Weighing Systems for Wiring and Mechanical Faults

Load cell weighing systems solve some of the knottiest problems in batch and level control by directly measuring masses of solids and liquids as they're accumulated, dispensed or conveyed. But the load cells must be installed and wired properly, and the load structure must be engineered and constructed correctly to distribute the measured load as axial forces on the cells. What appear on the surface to be simple wiring and construction tasks have caused more than a few problems during commissioning and maintenance due to miswired or poorly made connections, distorted or binding structures, incorrectly installed load cells or rigid connections to adjacent equipment.
Such problems often are not found until a new installation is being…

Smart Drives, Mechatronics, Variable-Speed Drives and More Power Options

MEDIUM-VOLTAGE AC DRIVE MV1000 medium-voltage ac drives combine compact modular design, high efficiency and a good MTBF rate. Smart Harmonics technology reduces input total harmonic distortion to less than 2.5% without filters, which exceeds the requirements of IEEE519-1992. It also provides galvanic isolation between power input and output, and uses two 5-V step bridges per phase to generate a 17-level, line-to-line voltage output delivered to the motor.

Since the goal is to control loop stability, the choice that gives you the best chance of that is the one to make.

Question:
Is there some general rule on when we should use =% (equal percentage) and when linear control valves? I know that the determining factor is the inherent flow characteristic, the flow vs. lift at constant pressure drop, or something like…

Embedded vision is everywhere around us. It's in our phones, cars, medical devices, grocery stores, gaming systems, factories and more. At the rate vision is being added to embedded systems, chances are you will need to have some knowledge of vision within the next few years. There are an enormous amount of applications that can benefit from adding vision because it enables machines or products to know more about their physical surroundings and how to interact with them. Embedded vision can also enhance safety by detecting danger and preventing accidents, boosting efficiency by improving the throughput and quality of manufacturing, simplifying usability, and fueling innovation by enabling designers to do things previously thought impossible. This video will explain how FPGAs can be used to accelerate the incorporation and use of embedded vision applications in your machines.

In this podcast, Ralph Rio at ARC Advisory Group talks with Jim Montague, Control's executive editor, about some of the latest innovations and best practices in collaboration tools and platforms used by process control engineers and their colleagues.

Safety is your number one priority. Unexpected risk to your operation is always just around the corner -- whether it be cyber security breaches, natural disasters, or disruptions to safe and smooth production. You need a tried and true platform you can trust to keep your plant running and intelligent tools to help you quickly remedy any situation, or better yet, help you prevent an incident before it even happens.In this video, Steve Elliott, director of product management for the Triconex brand discusses the benefits of having an integrated control and safety system. This video was filmed at the 2013 Foxboro and Triconex Global Client Conference in San Antonio, TX.

Instruments -- as well as the technicians who work with them -- are foundational to the Invensys "enlightened plant" vision. In this video booth tour from the 2013 Invensys Foxboro & Triconex Client Conference, Scott Hill and Rogier van Dijk demonstrate the capabilities of the company's Foxboro Evo Maintenance Response Center, including "plain text" device error messages designed to make technicians far more productive in their routine troubleshooting tasks. Watch the video.

Systems upgrades can be painful and costly. Invensys knows this, so it has smart guys like Graham Bennett, senior principal migration consultant, whose job is to help users of competitive systems to migrate to Invensys as painlessly as possible. Similarly, he helps existing Invensys customers move forward while keeping as much of their asset investments as possible. Filmed at the 2013 Foxboro & Triconex Global Client Conference in San Antonio, Texas, Bennett demonstrates different ways he handles migration with old or competitive equipment where there's no reengineering or intellectual property changes required.
